Ferrite materials contain a large amount of iron and oxygen ions, which form strong magnetism through magnetic interactions. This type of magnetism has the characteristics of high temperature stability and high saturation magnetic induction strength, making ferrite widely used in the manufacturing of electronic components, electromagnetic devices, and electric motors.
Ferrite has low price, high temperature resistance, and is not easily oxidized.
Rust Resistant. Suitable for use in Fresh or Salt Water. Magnetism Will Last Lifetime with Normal Use.
The advantages of ferrite lie in its rich source of raw materials, high cost-effectiveness, excellent chemical stability, no need for surface treatment, and high temperature resistance.
Applications: Science Educations for School, Kids' Science Projects, i.e. Levitation Train, Home Crafting, Light Holding Jobs in Backyard or Garage, Magnetic Therapy for Pain or Bug Stings. Holding Assemblies and Tools. Gifts.
Ferrite materials have good conductivity. And It is a typical semiconductor material. It has excellent mechanical properties and thermal stability in high-temperature environments, making it a material with good heat resistance and high temperature resistance.
